Expected Statement error when using multiple parameters in VBS - vbscript

Question

I am working on making a simple vbs that will open and close an excel file and save as it closes. This is to update the values inside the excel file after they are modified by a separate python script, and I need to do it this way for many dumb reasons outside my control.
I don't have a lot of experience with VBS but what I researched about this, I don't see the error in my code. However, I get an error whenever I try to run the code below. There error is:
Line: 7
Char: 39
Error: Expected statement
Code: 800A0400
Source: Microsoft VBScript compilation error
Any help would be appreciated, thanks!
dim fso
set fso = CreateObject("Scripting.FileSystemObject")
if(fso.FileExists("C:\Users\Public\Documents\Templates\testfile.xlsx")) then
set xlapp = createobject("Excel.Application")
xlapp.Workbooks.Open "C:\Users\Public\Documents\Templates\testfile.xlsx"
xlapp.ActiveWorkbook.SaveAs Filename:="C:\Users\Public\Documents\Templates\testfile_test.xlsx", FileFormat:=51, ConflictResolution:=2
xlapp.ActiveWorkbook.Close SaveChanges:=True
end if

If you are using standalone VBS, the following lines won't work because VBS isn't VBA. VBA supports Named Argument Syntax in function calls whereas its not supported by VBS
xlapp.ActiveWorkbook.SaveAs Filename:="C:\Users\Public\Documents\Templates\testfile_test.xlsx", FileFormat:=51, ConflictResolution:=2
xlapp.ActiveWorkbook.Close SaveChanges:=True
You have to provide the arguments to the function. So Function ArgName:=ArgValue becomes Function ArgValue
xlapp.ActiveWorkbook.SaveAs "C:\Users\Public\Documents\Templates\testfile_test.xlsx",51,,,,,,2
xlapp.ActiveWorkbook.Close True
